Hello mushroom friends,
I'm stuck with this unusual, exciting find:

Morphological features:

Location: On a debarked hardwood branch, fished out of a pool with stagnant water, the branch was completely submerged
Growth form: The fruiting bodies grow around Annulusmagnus triseptatus. It looks like the mushrooms eat up Annulusmagnus.
Fruit body shape: like lying eggs
Fruit Body Width: Approx. (130) 142.8-172.7 (176.2) µm
Color: yellowish with brown encrustations

The fruiting bodies consist of a brown encrusted outer shell, a white inner shell. Both ovoid.
Inside the inner shell are spores and oil droplets
I could not discover any asci or paraphyses, but spores, so it should not be a clutch:

The spores:
globos, warty, burrs between warts form incomplete web
Dimensions:
(3.6) 3.64 - 4.5 (5.4) x (3.3) 3.5 - 4.1 (4.2) µm
Q = (1.0) 1.02 - 1.2 (1.3); N = 28
Me = 4.1 x 3.7 µm; Qe = 1.1

Do you have a bright idea?
Best regards
Dieter
